Total cross sections for double photoionization of He by high-energy photon impact are evaluated by use of the correlated double-continuum wave function. Calculated ratios of the double- to single-ionization cross sections are compared with the very recent observations by Levin and co-workers [Phys. Rev. Lett. 67, 968 (1991); Phys. Rev. A 47, R16 (1993)]. The role of the final-state correlation is also examined.
